Application filed September 8, 1921. Serial No. 499,163.

Too-ll whom it may concern:

Be it known that I, Ti lman; J. F. Bon'r'ronnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Cue-Trimming lVIachines, of which the following is a specification.

The present invention has reference to cutting machines and particularly to machines adapted for cutting and trimming cueends and tips.

One object of the inventionis to provide a machine of this character by means of which the end of a cue can be completely out off, tenoned or the tip trimmed to the desired size and shape. I

Another object is to provide a device of this character by means of which the depth of the cut forcutting off the tip to a diameter equal to that of the one end is attained, with the result that the tip will form a per- .fect and smooth continuation of the body. of

the cue.

Another object is to provide a device of this character whereby the cue may be supported in different positions so thatthe one tip can be out on an angle to produce a flaring continuation of the body. Another object is to, provide a device of this character by means of which the cue can be easily and accurately fed toward the cutter, as the cutting proceeds.

Afurther object is to provide'a device of this character which having once been set to cut a tenon of a certain-diameter, no further adjustments 1 are necessary, matter what the original diameter of the one end may be. i j

A still further object is to provide a device of this character which-will cut off the end of the one and trim the fiber without re uiring original adjustment.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings. i

In the drawings: Figure 1 is a top plan chine; Figure is a side elevation of the same. Figure 3 is a vertical transverse section on the line 3 3 of Figure 2.

Figure 4 is an enlarged vertical longitudinal sectional view Figure 1.

on the line 4.-4 of Figure 5 is a vertical transversev section on the line 55 of Figure 2.-

Figure 6 is a slightly enlarged elevation of the cutter and one end, showing the stop or gage for regulating the depth of the cut into the cue tip. I r Referring particularly to the accompanying drawings, 10 represents a casing which has a screw clamp 11 for attaching the same to the. edge of-a table. In this casing are supported the shafts 12 and 13, the former carrying a large gear 14:, while the other shaft carriesa smaller gear 141*, said smaller gear being in mesh with the larger gear and being driven thereby. On the outer end of the shaft 12 is mounted a crank handlel5,

by means of which the gears are rotated.

The other shaft 13 extends a short distance beyond the other side of the casing and through a bearing sleeve 13*,1and has on its outer end the rotating'cutter 16. In the outer end of the cutter there formed a socket 16', in which is received the stem 17 of the cutter stop or guide 18. It will be noted that the diameter of the stop 18 is equal to the diameter of the cutter, that is the outer peripheral face of the stop lies in the same plane as that of; the outer faces of the spiral cutting ribs of the cutter.

This arrangement prevents the cutter from cutting the end of. the one, or the cue tip, deeper thanthe external surfaceof the body of the cue.

Supported on the bearing sleeve 13 is a block 19, and extending outwardly from the block, and in a direction away from the cue, said. fork being adjustable laterally.

Formed on the block 19 are the eyes 23 through which slides a transverse oppo sitely threaded shaft or rod 24c, and threadedly supported on this rod are the jaws 25 of a vise, and between which aws the tip portionof theme is held while being acted The block l9'has the threaded sockets 27 in which are secured the threaded rods 26 and 28. On the outer ends of the rods 26 and 28 are engagedthe nuts 29 and 30, the former being a single nut while the latter represents a pair, one of which 30 being a jam nut. The rod 24 is positioned lengthwise between the nuts 29 and 30 and it is adapted to be moved in the direction of its length by turning the nut 29 so that it bears against one end of the rod and pushes said rod forwardly. The nut 30 operates as a stop to limit this movement of the rod when the rear end of the latter strikes said nut. As the rod carries the cue-holding jaws 25, the cue is fed to the cutter 16 by advancing the rod 24 as described.

Carried by the block 19, and projecting therefrom in parallel relation to the cutter, is a stop bar 31, against which the tip end of the one is engaged'to regulate the length of the cut thereon by the cutter. The block 19 is removably mounted on the sleeve 13 and it is also adjustable thereon in the direction of'its length. The block is secured in adjusted position by a set screw 33 carried thereby and engageable with the sleeve.

'As the block 19 carries'the supporting rod 5240f the cue-holding jaws 25, and said block is adjustable along the sleevel in a direction-parallel to the axis of the cutter 16, the jaws can be correspondingly adjusted to properly position" the work to the cutter to obtain a cut of the desired length.

Vifhen a cue end is to be cut oil, the stop member 18 is removed, and upon turning the handle, the cutter will be rotated. The operator turns the nut 29 which bears against the adjacent end of the rod 24;, with the result that the rod 24: is advanced until the other end of said rod abuts against the adjacent nut 30. It will be noted that the rod 24' slides throughthe guide eyes 23, and when the rod has come into contact with the nut 80, the cutter has removed the desired amount of material from the cue end, or the tip thereof. It will be understood of course, that during the operation of the cutter the one must be rotated by the operator so that the cutter may operate all the way round the cue. The jaws 25 must be adjusted to firmly hold the one, but not so tight as to prevent the cue from being rotated as stated.

After cutting the tenon to the required size, a rawhide ferrule is placed on the tenon,

and it is necessary to turn this ferrule down to the exact diameter of the adjacent portion of the body of the cue. This is done in the same manner as when cutting the tenon, ercept that the aws, and other parts are adjusted to different positions, and the jawsand cue are fed toward the cutter through a shorter distance. 'By adjusting the fork of the butt end support toward one side or the other, the one will be held at an anglewith menses respect to the cutter, and by this arrangeinent the cutter will cut the ferrule so that it will have an outwardly flaring end.

What is, claimed is:

1. A one trimming machine including a rotatable cutter, a block, a cutter shaft, a clamp for a one end slidably mounted 011 the block 7 for movement toward and away from the cutter, adjusting means for the clamp slidable in the block, a feeding means for moving the clampbodily, and a stop means adjustable into different positions to limit the movementof the clamp.

2. A. cue trimming machine including a support, intergeared shafts on the support, a rotary cutter carriedby one of the shafts, a bearing sleeve for the cutter shaft, a block removably supported on said sleeve, cue holding jaws adjustably carried by the block, and means on the block for limiting the movement of the jaws toward and away from the cutter.

3. In a cue-trimming machine, a support, a rotary cutter carried by the support, a block carried by the support'and adjustable in a direction parallel to the cutter axis, a cue-holder carried by the block and positioned to locate the cue alongside the cutter, said cue-holder being also adjustable in a direction transverse of the cutter axis, and a stop carried by the block and positioned for engagement by the cue-end, said stop being adjustable in a direction parallel to the cutter axis. 5 i

4;. In a cue-trimming machine, a support, a bearing sleeve projecting from the support, a shaft ournaled in. said bearing sleeve and projecting therefrom, a cutter carried by the projecting end of the shaft, cue-holding means positioned to locate the cue end alongside the cutter, and a support for the cue-holding means carried by the bearing sleeve, said holding means being adjustable on the support in a direction transverse of the cutter axis. I

a bearing sleeve projecting from thesupport, ashaft j ournaled in said bearing sleeve and projecting therefrom, a cutter carried by the projecting end ofthe shaft, cue-holding means positioned to locate the cue-end alongside the cutter, and a support for the cue-holding 'means carried by the bearing sleeve, and adjustable in the direction of the length of the sleeve, the cue-holding means being adjustal'ile on the supportin a direction transverse of the cutter axis.

In testimony whereof I afiix my signature.
